location desired whether it be in a ship, building, it

rolling stock or elsewhere.

An object of the invention is the provision of a hanger which is easily,quickly, conveniently and satisfactorily assembled for support anddisposition of cables, pipes, conductors and the like, of the same ordifferent diameter; in suitable arrangement in, ships, buildings,rolling stock and other places.

A further object of the invention is the'provision of a hanger whichwill securely hold cables and the like without becoming loosened due toexcessive vibration in the structure to which the hanger is attached. I

The present invention has been subjected to vibration tests at the rateof 4000 strokes per minute, and has been found to remain tight after 60minutes continuous vibration. Despite the fact that the present hangersecures the work firmly in place without loosening due to vibration,still the hanger is rapidly assembled or disassembled as the necessityarises.

The invention has for a further object a hanger which is inexpensive incost to manufacture and is generally superior to devices now known tothe inventor.

With the above mentioned and other objects in view, the inventionconsists in the novel and useful provision, formation, construction,association and relative arrangement of parts, members and features, allas shown in a certain embodiment in the accompanying drawing, describedgenerally and more particularly pointed out in the claims.

y 3 Claims. (o1. 24s cs) Fig. 8 isa modified form of screw adjustmentfor the locking spring.

Referring now to the drawing:

We provide a hanger bar I, formed and constructed to suitablyaccommodate a U-shaped strap clamp 2, of which there may be a pluralityand of different sizes, which clamp is held to said hanger bar by aspring locking keeper 3. The hanger bar may take any form desired, butpref,- erably. should be of channel cross-section as best illustrated inFig. 2. The hanger bar includes a base portion 4 and two leg portions 5and 6. The bar includes aportion 1 upon which the work is disposed, withtwoangularly bent ends 8 and 9 adapted to be secured in any convenientmanner to depending supports Illand ll attached beneath the flooring orother structure vIi. In the present instance we secure the ends 8 and 9to the members I0 and II respectively by means of bolts designatedgenerally as l3. The :base 4, and specifically the portion I, isprovided with one or more elongated slots I4. These slots are of suchwidth as to accommodate the strap clamps 2 and provide ledge portions l5and I6 on opposite sides of the said slots adjacent to the legs 5 and 6.

The clamp 2 may be of any form desired and of a size to best accommodatethe work. In the present instance, the clamp includes two legs I! and I8interconnected by a curved portion IS. The legs adjacent the ends areprovided with transverse openings 20. In the present instance the saidopenings are shown as of rectangular section.

The spring locking keeper 3 includes two leaves 2| and 22 interconnectedby member 23. The construction is such that the said locking spring isresilient in character and the said leaves tend to separate. Leaf 2i isprovided along its marginal edges with angularly related wings or lugs24 and 25. We preferably so arrange the said wings that they subtend anangle of 45 relative to the plane of the leaf 2|, and said wings arelikewise positioned intermediate the ends of said leaves. The leaf 2| isprovided in its outer end with a threaded bore 26 to accommodate a screw21 which is fiat-ended as shown in Fig. 6 for engaging the under side ofthe leaf 22.

In the modification shown in Fig. 8 the leaf 22 of the spring lockingkeeper 3 is provided in its under side with an indentation 28 inalignment with the threaded bore 26, and a screw 29 with a pointed end30 is threaded through said threaded bore 26 with said pointed nd ofsaid screw received by said indentation 28 for centering said end ofsaid screw.

The operation, uses and advantages of the invention are as follows:

Reference is made to Fig. 4, wherein a cable 3| is transversely passedover the hanger bar I and held to, hanger bar by meansof the clamp of;Fig. 3 and the, spring locking keeper of Fig. 5. When the proper sizedclamp has been selected, depending upon the diameter of the work, theclamp transversely straddles the cable, with the ends of said clamppassed through one of the longitudinal slots I4 oi the han er bar and insuch position that the openings 20 lie beneath the base 4 and in thezone of the, legs. 5 and B. The spring locking keeper 3 is of suchlength as to be transverselyaccommodated between the legs 5 and 6 of thehanger bar. The leaves of the spring locking keeper 3 are compressedtogether, and thelugs 24 and 25 are passed through. the openings 2]! oftheclamp. The screw 21 may already be in position between the leaves,but moved outwardly so as not to interfere with compression of theleaves, whereupon the screw is turned to forcibly separate the leaves attheir outermost ends, as for instance illustrated in Figs. 5. and 6.Obviously, the outermost leaf'22 will engage the base 4, resting on theledges l5 and L5 and spanning the slot I4. As the screw 21 is turned,the lowermost leaf 2| is moved downwardly to, bring the lugs 24 and 25into tight engagement with that portion ofthe clamp 2 bounding theopenings 20 The tension of the leaf 2| or the locking spring keeper 3holds the screw against counter-rotation, and the clamp tightly holdsthe work against the hanger bar. It is evident that any vibration thatoccurs in the structure would be communicated to the work through thehanger bar, and bythe work and hanger bar to the spring locking keeper;The net result is that vibration does not loosen the screw 21 northelocking spring from its engagement with the strap.

In Fig. 1' we have shown an embodilment Wherein a series of cables ofdifferent sizes are conveniently carried on the hanger bar.

We claim:

1., A hanger including ahanger bar upon which .work is supported, a Ueshaped clamp extended over the work and through said hanger bar, saidclamp being provided with openings in its ends, a spring locking keepercomprising a single piece of sheet metal bent upon itself and formedengaging said clamp for drawing said clamp upon the work and clampingthe work upon said ha e b 2. A hanger as characterized by claim 1including means for adjusting the tension of the spring leaves of thespring; locking keeper upon the work clamp.

3. A hanger as characterized by claim 1 including an adjusting screwthreaded in one of the leaves of the spring locking: keeper and engagingthe other leaf of said keeper for adjusting the tension of said keeperupon the work'clamp.
